Operation Marshall

Operation Marshall (6-11 August 1950) was a military operation of the Korean War launched by the United States and South Korea. Considered to be the crushing blow that ended the Pusan Perimeter campaign, it resulted in the US and South Korean recapture of Chonju, Taechon, and ultimately Seoul from the North Koreans.

Operation
Following the success of the Yongju-Chongju Gap campaign and the Battle of Chonju, North Korean forces on the western shore of South Korea were trapped: they had to face United States and South Korean forces to the south at Chonju and US forces to the east at Chongju. The offensive began on 6 August with a large attack on Taejon from recently-liberated Chonju, and US forces in the east launched an assault on Kongju from Chongju. By 7 August, the forces in the south and west had met up at Ch'onan to attack the North Koreans there, having liberated Taejon, Kongju, and other villages in the way. On 8 August, the North Koreans in Ch'onan were decimated, leaving only four North Korean regiments between the Allies and Seoul. On 9 August, the UN forces reached Yong-in, just 20 miles to the south of Seoul. By 11 August, they had secured Suwon, Ansan, and Songnam-si, facing only one North Korean division on the way. At the end of that day, they did battle with North Korean forces in the city, and the capture of Seoul marked the defeat of the North Korean forces in the Pusan Perimeter. Operation Marshall effectively ended North Korea's offensive war in the south, and the war would become a stalemate along the Korean DMZ for the rest of the war.
